The belief that there is only one God.
Many religions, such as Christianity and Islam, are based on monotheism.
Monotheism is formed from "mono-" (meaning one) and "theos" (meaning god). The word describes the belief in a single god.
Think of 'mono-' meaning one and 'theos' meaning god — this helps you remember that monotheism refers to the belief in one god.
